Wi-Fi connections are inherently unstable and vulnerable to bad actors. Wired connections avoid these issues. Powerline adapters, which are extremely simple to set up, turn a long-range Wi-Fi connection into a wired one by using your home’s electrical network. This makes it much more stable and less vulnerable but with the same if not better range and strength. You don’t need to broadcast your network’s name or even use a Wi-Fi signal at all if you’re using these.
